将居住权制度纳入《民法典》，对我国的用益物权制度的完善意义重大，不仅为处理居住权纠纷提供了法律依据，其例外规定也为拓展居住权的经济功能提供了空间。然而，《民法典》关于居住权制度的规定较为简略，对其设立与消灭的规则设计较为概括，也居住权与其他权利之间的冲突与协调。因此，有必要通过解释论厘清合同型居住权的规则，协调好合同型居住权与其他权利的冲突。

本文主体部分一共四章，第一章主要从历史角度概述了居住权制度的相关内容。内容涉及罗马法时期的居住权、域外对居住权制度的发展情况以及我国居住权的立法过程和功能拓展，为我国合同型居住权相关规则的研究奠定基础。接下来具体分析合同型居住权的规则与适用。第二章的内容侧重于合同型居住权的设立规则。第一，居住权人的主体范围应不限于自然人。第二，居住权的客体包含了住宅的组成部分及住宅的附属设施。第三，对于合同型居住权涉及的权利与义务。其中居住权人应当享有占有、使用住宅及其附属设施、依约享有住宅收益、适当改造和修缮房屋等权利，同时也应承担妥善管理住宅、及时返还住宅等义务；

所有权人享有住宅收益和处分权利，同时也应承担住宅的重大修缮义务。第四，对于合同形式，不宜因缺乏形式要件而直接认定居住权合同无效，应当综合认定口头居住权合同的效力。第五，对于合同型居住权的登记规则，未登记的居住权不具有对抗第三人的效力，但居住权人可以基于居住权合同要求所有权人履行登记义务。第三章分析了合同型居住权的消灭规则。除了《民法典》规定的消灭事由，还存在基于合同解除、所有权人穷困抗辩、居住权人放弃、滥用权利等其他法律行为。第四章主要讨论了居住权与其他权利之间的冲突处理。本文主要涉及两类冲突。第一种是与抵押权的冲突，在两项权利均登记的情形下，若抵押权先于居住权成立，则所有权人应取得抵押权人的同意才能设立居住权。若居住权先于抵押权成立，所有权人只需及时告知居住权人即可，住宅上的居住权不受影响。第二种是与租赁权的冲突。根据出租人的不同，可以分为居住权人和所有权人。若出租人为居住权人，应优先保护租赁权；若所有权人为出租人，后设立居住权不能对抗设立在先的租赁权，类似于买卖不破租赁。通过上述研究，旨在厘清居住权的适用规则，并为司法实践提供相应的借鉴。

Incorporating the institution of habitation rights into the Civil Code has significantly advanced the perfection of our usufructuary rights system, not only by providing a legal basis for resolving disputes over habitation rights but also by broadening the economic potential of habitation rights through exceptional regulations. However, the Civil Code's provisions on habitation rights are relatively concise, with general rules regarding their establishment and termination, and less attention to the coordination between habitation rights and other rights. Therefore, it is imperative to clarify the norms of contractual habitation rights through interpretative analysis and reconcile the conflicts between contractual habitation rights and other rights.

This paper is structured into four chapters. The first chapter, from a historical perspective, outlines the essence of habitation rights, covering Roman law's habitation rights, international developments, and the legislative journey and functional expansion of habitation rights in China, thus establishing a foundation for studying contractual habitation rights. Proceeding to delve into the norms and application of contractual habitation rights, the second chapter emphasizes rules for their establishment. Firstly, the subject of habitation rights extends beyond natural persons. Secondly, the object encompasses parts of dwellings and ancillary facilities. Thirdly, regarding rights and obligations under contractual habitation rights, the holder should possess, use the dwelling and facilities, enjoy agreed-upon benefits, modify suitably, and maintain and repair, while also manage well and return timely; the owner enjoys the right to dispose and benefits, but also bears the duty for major repairs. Fourthly, oral habitation contracts should not be deemed invalid solely due to formal defects, but their effectiveness should be comprehensively assessed. Fifthly, unregistered habitation rights lack third-party effectivity but the holder can demand registration based on the habitation contract. Chapter three examines the termination rules of contractual habitation rights, which, besides those stipulated in the Civil Code, include termination by contract, owner's plea of hardship, abandonment by the holder, and misuse of rights. Chapter four discusses conflicts between habitation rights and others. Primarily, conflicts with mortgage rights, if both are registered, require the owner to obtain mortgagee's consent if habitation rights follow, but only inform the habitation right holder if habitation rights precede, unaffected. Second, with leasehold, depending on the lessor being the habitation right holder prioritizes leasehold or the owner, latter established habitation rights cannot contest prior leasehold, akin to sale not breaking lease. This research aims to clarify habitation rights' application rules and provide practical guidance for judiciary practices.
